Abstract: A stent retriever assembly having a proximal end and a distal end and including a mesh tube having a distal and proximal end and being connected to a first wire. Also, a blood-porous fragment guard is at the distal end of the mesh tube and has a central hub and extending radially and proximally from the central hub. Further, a second wire is connected to the central hub, and when this second wire is pulled proximally relative to the first wire, the hub is pulled proximally, which thereby causes the fragment guard to deploy in expanded form.

Abstract: A stent retriever assembly having a proximal end and a distal end, and including a mesh tube having a distal and proximal end, and being connected to a first wire. Also, a blood-porous fragment guard is at the distal end of the mesh tube, the fragment guard including spokes joined at a central hub and extending radially and proximally from the central hub, and wherein a second wire is connected to the central hub so that when the second wire is pulled proximally relative to the first wire, the hub is pulled proximally, causing the spokes to spread out and causing the fragment guard to widen.

Abstract: An aneurysm closure device that includes a retention assembly, adapted to retain the closure device in place on an aneurysm neck. Also, a seal has a wire frame, defining a set of eyeholes and thread, threaded through the set of eyeholes, to form a lattice. Finally, an expanse of silicone, is cured onto the thread, to form a barrier.

Abstract: A medical catheter that has a medial section having twin lumens, each enclosing a separately controllable wire control unit, proximal to said medial section, permitting a user to control said wires; and a fossa distal to said medial section, enclosing an expandable device that may be deployed to have a distal, clot fragment guard section and a proximal clot disrupting section and which is orientation controllable by said wires.

Abstract: A catheter assembly for implanting a medical device, comprising a first wire and a second wire, electrically insulated from each other, attached to the medical device at a first attachment point and a second attachment point, respectively. The first wire defines a first region susceptible to electrolytic disintegration, by passing an electric current through it, contiguous to a the first attachment point. Similarly, and the second wire defines a second region susceptible to electrolytic disintegration, by passing an electric current through it, contiguous to the second attachment point. Also, there is a separately controllable electric supply for the first and the second wire, so that the first wire may be disconnected from the medical device, without disconnecting the second wire.

Abstract: An aneurysm closure device having a pair of retention clips joined together. Each of the clips has an aneurysm anchor joined to a root-vessel anchor, and is made of material having a resilient installed state, in which the aneurysm anchor and the root-vessel anchor are urged together, thereby squeezing and being retained by interposed tissue. Also, an aneurysm seal, to seal an aneurysm, bridges the clips, causing the aneurysm to atrophy.
